WILLIAM A. TURNER, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO EDMUND CONVERSE, OF SAME PLACE.

' SELF-.CLOSING FAuoET.

SPECIFICATION forming part ef Letters Patent No. 531,484, dated Deeembei` 25, 1 894.

Application tiled June 28, 1890.

To all whom t may concern,.- K

Be it known that I, WILLIAM A. TURNER, a citizen of the United States, and a resident ot' Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Self-Closing Faucets, of which the following is a specification, containing a full, clear, and exact description of the same, accompanied by drawings forming a part ot the same, and in which- Figure 1Y represents a sectional view ot' a self closing faucet embodying my invention. Fig. 2 is a sectional View ot' the end wall of the variable chamber and showing the adj usting screw by which the air vent to the chamber is regulated. Fig. 3 is a top View of the wires forming the cage by which the lower Valve to the variable chamber is retained in place, and Fig. 4 is an end view of the adj usting screw, by which the air vent to the variable chamber is regulated.

My invention relates to that class of faucets in which the water Way is automatically closed when the force employed in opening the valve has been removed, and it consists in the construction and arrangement of parts as hereinafter set forth and specifically pointed ontv in the subjoined claims.

A denotes the shell forming the body of the:

faucet.

B is a stuffing box cast integrally with the shell A and C is a partition also cast integrally with the shell A and provided with an opening C', which is surrounded with'an annular valve seat C2. Extending downward from one end of the partition C and integral with it is the wing C3, cutting oft the upper Y portion of the passage through the shell A 5o the packing disk H and through the opening C,^thereby preventing the current of water carrying sand or grit from passing across the surface of the packing disk.

. The shell A has a screw threaded 'opening D in which is screwed the cylindrical shell E .open at its upper end and containing the piston E comprising the shell F having a screw threaded opening F in which is screwed the tubular shell G having at its lower end the outwardly projecting flange Gf and at its upper end the hole G2 communicating with the interior ot the shell F. "Between the lower end ot' the shell F and the flange G' are the packing rings G3 forminga watertight joint with the side wall of the cylindrical shell. The side wall of the shell F is provided with small holes F*, and within the shell F is placed the valve disk F? by which the hole Gr2 is closed, a spring F3 pressing upon the valve disk F2 to hold it down and secure the certain closing of the hole G2 upon the upward movement of the piston.

A packing disk H is placed upon the upper surface of the shell F, held in place by the nut H which is held upon the screw threaded section ot the short stern H2, and as the piston E rises the disk H is brought against the annular valveseat C2 closing the opening C.

I denotes a hollow boss projecting inwardly from the end wall E2 of the shell E, and having the shoulders I upon which rests the Valve disk I2. A

I3 is a screw held in theV end wall E2 and concentrically with the hollow boss I, having a V shaped slot l4t forming a vent hole at the side ot' the screw, which is enlarged or diminished as is required by withdrawing the screw or vice versa. The screw I3 is also yprovided with a tianged head I5, in order to prevent thek screw from being entirely withdrawn, and above the valve disk I2 are placed the crossed wires I6 attached to the end .of the hollow boss I, in order to prevent the disk I2 from bein'g raised out ot' its position or being displaced.

J denotes a spiral spring within the chamto receive the valve stem H2. Packing rings K2 in the box B serve to form a water tight joint around the spindle K.

K5s denotes a screw threaded metallic ring by which the rings K2 are compressed. K'1 is a hollow screw held in the upper end of the stuhng box, and projecting a short distance above the shell A.

K5 is a check nut upon the hollow screw KL1 and resting against the shell A.

Pivoted to an arm N cast integrally with the shell A is a lever handle, in which is pivoted the friction roll N2 with its axis lying in the plane of the axis of the spindle K, so that as the spindle is depressed by the pressure upon it of the friction roll N2 the axis of the roll will move through a small arc substantially corresponding with the plane of the axis of the spindle K. By this arrangement of the roll and spindle the pressure applied to the spindle will always be in a line coincident with its axis, thereby preventing any lateral pressure, which would tend to carry the spindle against the packing in the stuifing box B.

The operation of my improved self-closing faucet is as follows: The valve disk H is held, in its normal position, against the annular seat C2, thereby closing the water way through the opening C', until the spindle K is forced down by the lever handle N', carrying the piston E downward into the chamber E3 and opening the water way C. As the piston E is forced downward, compressing the spiral spring J, the valve disk I2 will be forced down upon the shoulder I closing the opening at the side of the screw I3 and causing the air in the chamber E3 to be forced out through the small openings F, passing through the hole G2 and lifting the Valve disk F2. Then the pressure is removed from the spindle K, the tension of the spring J will force the piston E upward closing the opening C', and during the upward movement of the piston E' the valve F2 is closed byits own gravity, the pressure from below having been removed, aided by the spring F3, which renders the closing of the valve F2 immediate and certain. The valve disk I2 at the same time is opened by the excess of atmospheric pressure from without, allowing air to iiow into the chamber E3 as the pistou rises. The downward sliding motion of the spindle K and piston E is limited by the adjusting screw K, which is raised or lowered as required to receive the contact of the friction roll N 2 and i limit the angular motion of the lever handle N', thereby varying the water way and consequent size ofthe stream. The upward movement of the piston E is regulated by the size of the vent I4, allowing the pressure of the atmosphere to co-operate with the tension ofthe spring in raising the piston and closing the opening C. The air inclosed within the chamber E3 also serves as a cushion to check the downward movement of the piston E', as its downward motion cannot take place faster than the {iow of airthrough the holes Ffi. The recess K is slightly larger than the diameter of the valve stem H2 as it enters the recess in order to allow for any slight variation that may occur in the alignment of the stem 112 and the sliding spindle K. The spindle K is provided with a flange K6 at its lower end to prevent the spindle from being pushed out through the stuiiing box by the water pressure. When the faucet is opened by the downward pressure upon the spindle K in the manner described, the water in flowing through the faucet passes below the wing partition C and rises around the upper end of the piston E iiowing through the opening C', the piston E acting as a Valve having an upward motion in a line parallel with the walls of the partition C and the wing C3.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a faucet comprising a shell A having a partition C containing a water way, and a valve disk closing said water way, the combination of a sliding spindle by which said valve disk is actuated, a stuiiing box inclosing said spindle, packing rings held in said stuffing box, a screw threaded ring K3 by which said packing rings are compressed, spindle depressing mechanism, whereby said spindle is pushed downward for the purpose of opening the valve, and a hollow screw K4 held in the upper end of said stuiing box and in the path of said spindle depressing mechanism, whereby the movement of the spindle is adjusted, substantially as described.

2. The combination of the shell A, partition C having a water way C', shell F having one end open and carrying a valve disk by which said water way is closed, a shell G closed at one end and provided with a hole G2 and having at its opposite end a flange G', said shell G having its closed end screw threaded and held in the open end of said shell F and a series of packing rings G3 between the shell F and the iiange G,`substantially as described.

Dated at Worcester, in the county of Worcester and State of Massachusetts, this 24th day of Julie, 1890.

WILLIAM TURNER.
